`Mounted lrinve {h e rolls 3ft are suitulilu `which bearings are capable of moving .to-

ward and from the roll 34 in a,support1ng frame 41 carried by the framework of the machine, a spring 42 being preferably ernployed to hold `the roll 39 yieldingly 1n contact with the opening roll 34.

Mounted in brackets 43 in front of the framework of the machine is the saddle 44, which is preferably .inverted V-shaped in crosesec tion, and a sprocket chain 45 ydrlven from the sprocket wheel 13 travels 1n a suitable track` or way 46, Fig. 3, mounted below `the apex of the saddle 45 and having f valves normally `ing` power on to the machine, y

shaft and the followers 47, which are secured to the sprocket chain 45 and pro]ect outward t rough a slot 48 in the front side wall of lthe saddle, said followers 47 being suitably spaced to advance the series of signatures along the saddle. i

For the I in the suc ers 22 at the proper instant, a series of cams 49, are mounted. on shaft 16 which coperate with the stems 50 of valves 51 in the pipe 24 (see Figs. 1 and 2). These drop by their own weight so as to open the pipes 24 to the external atmosphere, but, at the instant when the suckers Vare'in action to pull down the folded ed of the signatures from the hoppers, the va' v es are closed by-the action of the cams 49 coming in contact with thestems 50 of the valves and raising the same.l

In like manner, the pipes 37 are provlded with valves whose stems52 extendv downward'in a position to be actuated by 'cams i 53 on shaft 18, the operation ofthe cams being so timed that thel .v,alves will'be raised to close the suction pipes 37 at the time when suction is desired in the ppeenmg rolls to hold one of the sides of "signature 1n contact therewith and the lstems 52 of the valves being released by lthe cam at the time when it is desired to release the side of the signature from the suction mouth of the roll.

For the purpose of operating the machine through a Very 'slight a wheel 54, Fig. `2, is, secured to the operator, by turning said wheel, may glve a slight movement to the 'parts of the mechanism.

At the instant when the signature 55, 3, is delivered to the belt -31 and isv in the act of beingreleased` bythe clamp 29L`of the signature-withrlrawing device 28, the Sucker mouth 35 on the opening roll 34 iS just approaching the point where the roll39 contacts with the roll 34, as clearly illus-4 ti'ated in Fig'. 3.

The further revo'- lution of the opening roll advances the signature until it escapes Ifrom between the rolls 34 and 39 and drops upon the saddle, as shown in Fig. 6. 4

Atween the rolls34 and 39, sucker mouth `35 When the signatures to be inset are com pound signatures,` that is, when the sheet is `folded more'than once, the signaturesare H placed in thehoppers with the closed edge `of the signature to the front of the machine (that is, to the right in Fig. 2) and with the open ed e to the left of said gure. If

the folds o the signature are Iparallel the upper side of the signature, thatis, the two upper leaves thereof, are united and the signature-withdrawing devices 28, in withdrawing t-he signature, turn it entirely over, so that the lower two leaves ofzthe si nature, when the same is placed upon the lt 31, are also united at their lower edge, while the two upper leaves are sepa-rated at their lower edge, that is, are not connected-by a fold. And `when the opening roll carries the lower leaf of the compound sigiaature around with it, it necessarily carries t e eaf" or leaves'rto vwhich the same is connec i by the signature at its' midy e portion, w ile all of the leaves of the signature above the middle portion advance in a line approximately tangent to the opening roll 34, as shown in Fig.'4,` so that, whether the signature be a compound or a simple signature, it is opened always at its middle,andthe signature thus opened is placed up'on the saddle; When the signatures, whether' sim le or compound, are placed upon the sa dle, they-are advancedby the followers 47 on the sprocket chain reaching a position in front ofthe next hopper and signature-withdrawing delthe fold at its lower ed e, thereby o ening vice in time to receive the next signature of tures from said conveyor and carrying one leafkthercof to one side of the support and permitting the other leaf'to project outwardj` signaturcs'nre fed open edge foremost, and
